Answer:
x=280
Step-by-step explanation:
We have, 15% × x = 42
or,
15
100
× x = 42
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 42 ×
100
15
x = 280
If you are using a calculator, simply enter 42×100÷15, which will give you the answer.
Answer: Last Option
Step-by-step explanation:
The initial height of the plant of species A is 25 cm and grows 3 centimeters per month.
If m represents the number of months elapsed then the equation for the height of the plant of species A is:
For species B the initial height is 10 cm and it grows 8 cm each month
If m represents the number of months elapsed then the equation for the height of the plant of species B is:
Finally, the system of equations is:
The answer is the last option
Answer:
Step-by-step explanation:
Alternate angles are angles that are opposite, on the other side of the lines, so imagine it as a z shape.
In this case, alternate angles include, 3, 13, other equal angles are vertically opposite, so that would include 7, 1, 15. Vertically opposite angles that are two angles made opposite with 2 intersecting lines.

33 photos in a 4x to 7x ratio
4x + 7x = 33
11x = 33
x = 3
33 photos can be put in a 4(3) to 7(3) ratio
which is a 12 to 21 ratio
so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7
Note:
<span>a(b) = ab = a x b = a times b</span>
1,068 is your answer. There will be 356 in each shipment because 1,424 divided by 4 is 356. And 356 times 3 is 1,068.
